1853: EJ is born, the youngest of the Federline children. Her father has a Quidditch background and later worked in constructing Quidditch equipment, placing the family at the 'top' of the working class and allowing all Federline children to achieve at least a few years of schooling.
1857-1863: Emilia demonstrates magical abilities in some relatively typical way. Her elder siblings go off to and leave school in some pattern, and eventually Nola leaves Ireland with her husband and gives birth to a daughter. EJ is generally too young to have an opinion about this. Shortly after her niece is born, the Federlines at home (Aidan, Erin, EJ, and Brennan) relocate to Scotland for improved Quidditch-marketing opportunities. Rory remains in Ireland and marries.
1864-1871: Emilia goes to school, where she is swiftly sorted into Ravenclaw. Her family's continued income and her own quick-wits allow her to stay in school; she earns a partial scholarship. After achieving seven OWLs, she lobbies to continue to achieve her NEWTs, determined to work in the Ministry when she graduates.
Which she does. After an extremely odd job interview, EJ begins working in the Department of Mysteries. You're not allowed to ask, but her specialty eventually becomes space.
1871-1874: And then she meets Kit Moony, an auror in the Department of Magical Law Enforcement. He's her other half and they balance each other out, and marrying him in 1874 and moving to Oxford is one of the easiest decisions she's ever made.
1875: Edison "Ned" Moony is born.
1878: Anne is born.
1886: The family moves to Pennyworth, in Hogsmeade.
1888-Present: Kit is kidnapped and missing for the next eight months; Emilia is never entirely sure whether he's alive or dead, and spends a great deal of her free time trying to stare down the auror's office until they give her more information. When he comes back he is not at all the same, and things finally explode when Kit physically attacks her and breaks three of her ribs. Rather than go to the hospital to have them dealt with and risk scrutiny, Emilia is instead healed by a friend who works in Hogsmeade Hospital.
Kit moves out a few days later. Emilia did not ask him to leave, but has not asked him to return.
Which brings her to the present. Holding things together for her children, and decidedly unsure what to do about her husband.
